Dr. Expert no comments

More than just a “cosmetic issue,” breast asymmetry can have negative psychological and emotional effects, according to the study by ASPS Member Surgeon Dr. Brian I. Labow and colleagues of Boston Children’s Hospital…

Comprehensive breast center improves quality of care for breast reconstruction

Dr. Expert no comments

Centralized breast cancer care at CBCs can lead to more timely breast reconstruction for women undergoing breast cancer surgery, suggests the study by ASPS Member Surgeon Albert H. Chao, MD, and colleagues of The Ohio State University, Columbus. …

Master heat-shock factor supports reprogramming of normal cells to enable tumor growth and metastasis

Dr. Expert no comments

The finding, reported by Whitehead Institute scientists this week in the journal Cell, lends new insights into tumor biology with significant implications for the diagnosis, prognosis, and management of cancer patients. Over the past several years, researchers in the lab of Whitehead Member Susan Lindquist have been investigating the role the transcription factor HSF1 plays in supporting malignancy. In normal cells, stressful conditions, including those caused by heat, hypoxia, and toxins activate HSF1, which serves to maintain protein homeostasis and helps the cells endure tough times. Cancer cells, however, are capable of hijacking this heat-shock response to their own benefit. …

Confronted with a harmful virus, the immune system works to generate cells capable of producing antibodies perfectly suited to bind and disarm the hostile invader. …

Thwarting protein production slows cancer cells’ malignant march

Dr. Expert no comments

From yeast to worms to humans, this stress response and its primary regulator, heat shock factor 1 (HSF1), help normal cells adapt to harsh environments, including the presence of heavy metals, high salt concentrations, low oxygen levels, and of course increased temperatures. "In a perverted twist of fate, cancer cells take advantage of this incredibly ancient survival strategy — the heat shock response — to help them survive despite the best efforts of our own natural defenses, and sophisticated therapeutics, to kill them," says Whitehead Member Susan Lindquist. "And trumping all that, we find it not only helps them survive, it helps them thrive!" Across tumor and cancer types, cancer cells rely on the heat shock response and HSF1 to support the production of vast quantities of proteins and the high-energy demands needed to propel malignancy…

Gene that controls aggressiveness in breast cancer cells identified

Dr. Expert no comments

The researchers, whose findings are published this week in the journal Cell, report that the ZEB1 gene is held in a poised state in basal non-CSCs, such that it can readily respond to environmental cues that consequently drive those non-CSCs into the dangerous CSC state. Basal-type breast carcinoma is a highly aggressive form of breast cancer. According to a 2011 epidemiological study, the 5-year survival rate for patients with basal breast cancer is 76%, compared with a roughly 90% 5-year survival rate among patients with other forms of breast cancer. …
